摘要
为了改善整流性负载下逆变器的输出电压畸变,首先提出了重复控制和电流预测控制相结合的控制策略,并分别对重复控制和电流预测控制进行了稳定性分析,然后给出了重复控制器和预测控制器的控制参数设计方法,最后在实验平台上对控制特性进行了验证。实验结果表明,重复控制能有效抑制整流性负载下的电压波形畸变,电流预测控制能提高系统的动态性能。
In order to improve the output voltage distortion of the inverter under rectifier loads, a control method which combines the repetitive control theory and the predictive control theory was proposed. Then the analysis of stability for repetitive control and the predictive control was presented, and the design method of the control parameters for repetitive control and predictive control was also given. The feature of repetitive control and predictive control was analyzed based on the experiment. The experimental results show that repetitive control can reduce the voltage distortion under rectifier loads effectively, and the dynamic performance of the system can be enhanced by means of current predictive control.
